I think it had something to do with the ridiculous humidity that
day, but I was pulling out the torch top of my Smith Acetylene/air
torch and ripped one of the tiny black o-rings. I asked at the place
I get my gas exchanged if they had any replacement ones and he looked
at me like I was crazy. I looked in Rio to see if they offered
replacements, my next guess was to call around, but I figured I’d ask
here first. I can’t imagine I’d just have to buy a new torch tip,
seems such a waste!

Another post said go to Smith, not a bad idea. We have a good
hardware store nearby - not “big-box”. They carry o-rings of all
sizes. Torch o-rings are no mystery, they’re just o-rings. The trick
is getting just the right size.

We have one of those places just outside of Milwaukee… It’s a
Tru-Value…

They have twenty running feet, on two sides, I kid you not, of small
drawered racks, with just about anything hardware related one can
dream of…And you can buy onsies…

Need a cotter pin…? One…?

How about a metric bolt what fits the handlebars on your dirt bike,
Yamahaha DT360…?

1/2-13 jam nut so you can use (this is not recommended unless you
are desparate) that wrond sided motor arbor so it won’t undo itself
when you use it…?
